The aim of the present study was to evaluate the suitability of low-cost carbon sources for bacteriocin production by Leuconostoc mesenteroides strain E131. For this purpose, inexpensive sugars derived from a sugar refinery plant (glucose, fructose and sucrose) as well as waste molasses were utilized as carbon sources in submerged shake-flask experiments and the kinetic response of the microorganism was evaluated. Interestingly, in the case of molasses, non-negligible decolorization-detoxification (up to ~27%) of the residue was performed together with the production of bacteriocin. In all instances the initial concentration of sugars employed was adjusted at 20 and 30. g/L, therefore the effect of both the nature and the initial quantity of sugar upon the growth of the microorganism was assessed. All media proved to be suitable for both biomass and bacteriocin production by L. mesenteroides, whereas variable quantities of lactate, acetate and ethanol were detected into the medium. Employment of fructose, sucrose or molasses as carbon sources resulted in the accumulation of mannitol (in some cases in significant quantities) into the medium; remarkable portion thus of the available or released fructose acted as electron acceptor instead of carbon source by the microorganism. The highest bacteriocin production achieved (=640. AU/mL) was obtained when initial glucose at 30. g/L was used as substrate. Finally, utilization of waste molasses as carbon source by L. mesenteroides resulted in satisfactory bacteriocin production (up to 320. AU/mL) besides the decolorization of the residue. © 2011 Elsevier B.V. |
